Supported Math(ing)

• Using AT in the Mathematics Process

2
Consider this...

• You went to the ATM machine and it would not give
  you 200 to buy groceries and fill your
  prescription refill because you had insufficient
  funds. You balanced your checkbook 2 weeks ago.
• How much money can you get from the ATM?

3
Consider this...

• You need to clock-in at work at 400 at the
  Burger King in the food court at the mall. You
  take the bus to work. The bus stop is one block
  from your apartment and the bus lets you out at
  the opposite side of the mall from the food
  court.
• When do you need to leave your apartment?

4
To solve these problems...

• What information do you need to have?
• What do you need to do with this information?

5
To solve it....

• What
• Process?
• Equation or formula?
• Estimation?
• Calculation?
• did you use?

Math(ing)

• Purpose
• To determine how much or how many
• To determine when or how soon
• Outcomes
• Measure (objects, time, amount, distance)
• Compute (totals, differences, values)
• Solve complex problems

7
Math(ing)

• Skills (Functions)
• Computing / Calculating / Measuring
• Exact amounts
• Estimates (e.g., nearest dollar strategy
• Process (Analyzing)
• Determine what type outcome is needed
• Select a formula (a math sentence)
• Fill in the values
• Determine the solution

8
Math(ing)

• Writing Math
• Why do we need to write math?
• What does writing math involve?
• What are AT tools for writing math?

9
AT for Math(ing)

• The purpose of AT is compensatory
• Therefore, the tools needed are those that
• Enhance or replace the skills
• Needed to produce math outcomes
• What AT tools do you use, know or have already
  seen in class?

AT for Math(ing)

• Tools for measuring
• What do we measure?
• Length or distance
• Elapsed time
• Amounts (number or volume)
• What are the barriers to measuring?
• What are the perceptual or physical barriers
• What are the cognitive barriers?
• What are the AT tools?

11
AT for Math(ing)

• Tools for computing
• What do we compute?
• Totals
• Differences
• Proportions / percentages (e.g., tips)
• What are the barriers to computing?
• What are the perceptual or physical barriers
• What are the AT tools?

12
What are the cognitive barriers to computing?

• Recall of
• Number names and number values
• 1 one / one one
• 3 ? ? ?
• Math operators - /
• Number facts
• Addition tables

• Equivalences
• Money equivalence (e.g., making change)
• inft, tspT, ozcup
• Computational rules
• Borrowing, carrying
• Fractions

What are the AT Tools?
13
What are the cognitive barriers to computing?

• Knowledge of
• Math logic basic processes
• One to one correspondence
• Math operations (add, subtract, multiply, divide)
• Math linguistics (e,g, spoken or printed words)
• Add, and, subtract, take away, more,
• Greater than / less than

What are the AT Tools?
14
AT Supported Math Strategies

• Many of the AT math tools are a combination of
• The tool (e.g., a calculator)
• AND
• A strategy
• Put 10.00 on the calculator
• Get items from the shopping list
• Subtract each items price as you put it in the
  cart
• Stop getting items when it says 0.00
• If the number starts with a - put the last item
  back
